Assessment method for remaining strength of corroded pipeline and its application;

Theory foundation for remaining strength assessment methodology is presented and assessing formula for relative assessment methodology is educed based on individual basic assumption.

API 579 and F101 are two kinds of common codes in computing the remaining strength of corrosion pipeline for local metal loss.

Residual Intensity Assessment of Liquid Ammonia Tanks;

Residual Intensity Evaluation after Corrosion of the Heater Tubes for Natural Gas and Life-Span Prediction

The near infrared spectra of sunlight or moonlight passing through atmosphere were measured by a CCD spectrometer in the instrument,then the central residual intensity of the water vapor absorption at 935 nm waveband was calculated and the total precipitable water in the atmosphere was derive.

Relationship between mass variation and residual strength change with temperature on 3D C/SiC composites in oxidizing atmosphere;

Analysis on wear depth and residual strength of downhole casing;

Analysis on residual strength after casing surface wear caused in casing drilling;

By analyzing the receive and release actuating cylinder,the undercarriage main tributary outer cylinder and the wing finishing inaccuracy and design theory remainder stroke for the problem of being out-of-tolerance of one model airplane actuating cylinder remainder stroke,the authors draw the conclusion that the accumulation of synthesis inaccuracy causes the problem of being out of tolerance.
